  </P
><P
>   You must own the operator class to use <TT
CLASS="COMMAND"
>ALTER OPERATOR CLASS</TT
>.
   To alter the owner, you must also be a direct or indirect member of the new
   owning role, and that role must have <TT
CLASS="LITERAL"
>CREATE</TT
> privilege on
   the operator class's schema.  (These restrictions enforce that altering the
   owner doesn't do anything you couldn't do by dropping and recreating the
   operator class.  However, a superuser can alter ownership of any operator
   class anyway.)
